What is the best sleep measurement device and/or app?
I use FitBit Versa, and it’s amazing. You can wear it while sleeping, walking, or working out, and the most exciting part? It’s waterproof and ideal for swimmers. I only wear it when I go swimming or for a walk. But I know it’s helpful for those who need to track their sleep patterns. I’ve tested it a couple of times. The device monitors your heart rate and movements all the time. It detects how much time you spend sleeping, awake, or restless.
